DISINFECTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 311,271, dated January27, 1885.

Application filed May 22, 1884.

.T 0 aZZ whom it may concern:

Be it known that I, RUssnLL THAYER, of the city and county ofPhiladelphia, and State of Pennsylvania,have invented new and usefulImprovements inDisinfecting Apparatus, of which the following is aspecification.

My invention has reference to disinfecting apparatus or hygienators; andit consists in a receptacle containing a disinfecting substance, andhaving an overflow-pipe connecting with the sewer or waste pipe to bedisinfected, and an inlet-pipe to admit water slowly into the saidreceptacle and cause it to flow through disinfecting material, and indetails of con struction, all of which is fully set forth in thefollowing specification and shown in the ac companying drawing,whichforms part thereof.

The object of this invention is to disinfect water-closets, waste andsewer pipes about houses or other places, and at the same time I provideapparatus to accomplish said result which shall be compact, efficient,and cheap to construct, and adapted to be used continuously orintermittently.

I11 the drawing is shown a sectional elevation of my improveddisinfecting apparatus or hygienator. v

A is a box, preferably lined with lead, but may be made of glass or anyother suitable substance and of any desired form.

B is a lid or cover, which is adapted to be locked.

O is an overflow-pipe, preferably of lead, and extends up through centerof the box A and terminates near the top; or it may enter the box at theside, if desired. This pipe connects with the water-closet or pipe H tobe disinfected.

D is a perforated or gauze diaphragm, and is supported in the box on alevel with the pipe 0, and is adapted to prevent the disinfootingmaterial, G, placed within the box from being shifted or clogging thepipe 0, but might be dispensed with, if desired.

E is a goose-neck water-supply pipe, and is provided with a valve, F,the said pipe extending into the box A and terminating near its bottom.If desired, this pipe might en (N0 model.)

ter the bottom directly; but the construction shown is probably thecheapest to make, as no soldered joints are required.

I is a check-valve.

The operation is as follows: WVa-ter is allowed to fiow through pipeEand circulates up through the disinfecting material G, becomingimpregnated therewith by the time it reaches the top, and passes abovethe diaphragm and fiows into the overflow O, and is conveyed to theplace to be disinfected. The box A remains full of water constantly, andas the flow is very slow the water has much time in which to becomeimpregnated with the disinfecting and deodorizing substance beforeescaping. By stopping the flow of water the apparatus is practically putout of action, and by turning the water on full it may be washed out.

In place of solid material a disinfecting-fluid might be used; but itwould require refilling more often than when solids are used.

\Vhile Iprefer the construction shown, I do not limitmyself thereto, asthe details of construction may be modified without departing from myinvention.

I am aware of the patents to Howard, No. 183,264., of 1876, 'Brown, No.131,422, of 1872, and Pike, No. 270,111,0f 1883, and claim nolhingtherein set forth or shown.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a disinfecting apparatus, the combination of a box, A, having thecentral overflowpipe, 0, the supply-pipe E, extending close to thebottom of the box and connected with the water-main, a valve, F, toregulate the flow of water through said pipe, and a checkvalve, I, toprevent siphoning of the disinfectant liquid from said tank,substantially as and for the purpose specified.

In testimony of which invention I. hereunto set my hand.

RUSSELL THAYER.
